Enabling branch office users to access local server when main office DC goes down


  • Hi,

    One of our clients has a main office with an SBS server with AD on it and some branch offices. Unfortunately they haven't got the budget to get a dc in each branch office, so whenever their DC goes down (which seems to be every few months as they get power cuts), their branch office users can't access the files in a file share on a local server in the branch site because of authentication issues. 

    So my question is, is there some kind of group policy like interactive logons that would enable the users to still access the shares on the local file server with cached credentials (without need to authenticate with the DC)?

  • You can not authenticate to a remote resource using cached credentials.

    I think you should increase resiliency of the AD services by adding some DC's on other physical locations (that are not impacted by the (same) power outages).

    You don't have to have a DC in each site for this, although this obviously has benefits.

    Management should weigh the cost of an additional server versus the cost of the outage of all branch offices. Probably the conclusion will be that a few thousand dollar a year can easily be invested in good infrastructure availability.
